For three years we have used synthetic and field data to investigate the effectiveness of commercial refraction tomography codes on both simple and complex subsurface velocity structures, with the ultimate goal of determining the suitability of the method for karst problems. The results of these studies indicate that refraction tomography is able to resolve karst features under some conditions....

Hydrogeological and Geochemical Characterization Both surface and crosshole tomographic geophysical data have been used in the saprolite and carbonate gravel (Areas 3 and 2, respectively) to delineate large scale geologic structure, nitrate plume boundaries, and localscale fracture zonation. Surface electri seismic data were originally used in a reconnaissance mode to choose the location for th...

The Spatial and temporal variability of soil properties (fluid composition, structure water content) hydrogeological employed for sustainable precision agriculture can be obtained from geoelectrical resistivity methods. For agricultural practices, site-specific information is paramount, especially at the planting season. An integrated one-dimensional (1D) two-dimensional (2D) electrical surveys...

Nikel menjadi sumber daya alam yang Indonesia miliki dengan jumlah sangat banyak. Sifatnya tidak dapat diperbaharui memerlukan pengelolaan sebaik mungkin agar manfaatnya dirasakan maksimal seluruh bangsa Indonesia. Undang-Undang Nomor 3 Tahun 2020 Tentang Pertambangan Mineral dan Batubara mewajibkan bagi penambang untuk melakukan pemurnian dalam negeri. Pada Januari 2023 terdapat 111 smelter ni...

The research area is in Block O Bunta Region, Banggai Regency. includes areas with laterite nickel deposits Central Sulawesi Province. Based on the Luwuk Sheet Geological Map, included Ku Formation (Ultramafic Complex) composed of serpentinite, gabbro, basalt, and schist rocks. aim this study was to analyze characteristics O, To achieve goal, several methods were carried out, namely field geolo...

Vertical Electrical Sounding (VES) and pumping test (constant discharge recovery test) was carried out in parts of Boki Local Government Area to evaluate the groundwater potential, using aquifer characteristics study area. Sixteen (16) VES point employed for this Schlumberger array, with a maximum spread 400- 600m. The stimulated result from field data shows 3-5 layers resistivity model followi...
